To all whom t may concern:

Be it known that I, MONROE J. MooNEY, a

l citizen. of the United States, residing at lel Cincinnati, in thecounty of Hamilton and State of Ohio, have invented certain new anduseful Improvements in Furnaces, of which the following is aspeciicaticn.

My invention relates tol an improvement in furnaces wherein adisintegrated. fuel is distributed over the fuel bed, in a series oflongitudinal sprays, Injector principles are.

utilized to feed the fuel through the nozzles conveying and distributingthe same by fluid pressure, andfsi-phonic action. The vapcrr` ,fluidpressure may be-.air or steam, or a combination of. both when abituminous fuei g conduits..

Y is used., dependent largely npon the percentage of "'moisture andvolatile `matter contained in the fuel. 'J

The velocity and density of the fluid pressure controlling the volume'of fuel .feed and vthe hydro-carbon mixture necessary to produce .theproper combustion and'maintain the thermal units within the furnace, is-

commensurate with the boiler pressures.

4The feed is automatically controlled by the furnace draft and boiler,pressure, offeringI a material economy in fuel consumption. as well asan increased efliciency' togetherx with a substantial elimination ofsmoke.

The object of my invention is to inject a disintegrated bituminous fuelwith a vaporsous fluid pressure into the combustion chamberofna furnacein a series of longitudinal Isprays with the velocity of the fuel feedand vvolume of the fluid pressure automatically controlled to'produce aproper Icombustion of the hydro-carbon mixture proportional to theboiler pressure,.to maintain a constant boiler pressure, or variableaccording to the exigency of pressure consumption.

Another object of my invention is to provide a furnaceof Dutch oven typewitha series of nozzles combined with the upper' surface wall, to injectjets of intermiixedv fluid pressure' and disintegrated bituminous fuelover the fuel bed. Y

l The features of my invention will be more fully set forth in thedescription of the ac.-v company' g drawings, forming a partV of thisspecification, in whichz'- Figure 1 is\ a central lvertical sectionthrough the fire box of the furnace as applied to a boiler. Fig. 2 is acentral vertical section on line w, Fig. 1, illustrating dia-y iSpecification of Letters Patent.

grammatically the stack damper regulator governed by the clraft andboiler pressures.

1, 2 represent the .side walls of'a boiler furnace.

3 represents hearth wall.

5x represents a horizontal type of boiler supported upon the side walls.

'lhe furnace is of a Dutch oveny type` with the lire:- chamber beneaththe boiler insteadl of projecting in front of the boiler customary insome types of Dutch oven furnaces. The Astyle of furnace however, isoptional., conditioned only in the provision of a reverberatory walllover the fire chamber, primarily for the reception of the fuel deliveryvthe front wall and f1 the 13 represents conduits through which the"-fue-l andi air blast is conveyed, each having a longitudinal slot 111formed therein di' rected toward the combustiorichamber 11.

The conduits serve as nozzles for jetting' sprays of fuel and vaporousfluid intothe combustion chamber. 'Thev rear end of each conduitisprovided with a stud projection 15 seated within an arch plate 16,forming the terminal for the furnace roof 10" serving as a reinforcementfor the roof as well as an edge' lining therefor. The lifev of the archis materially lengthened, as the arch plate 16 is a metal plate integraltheentire width of arch, and remotable, enabling the same to be readilyrenewed.

The forward end of the conduit, exterior of the furnace, is providedwith an injector. 17, in which 18 represents the fuel supply conduit,and 19 the fluid' furnace conduit, lthe pressure producing a siphonicaction at the junction ofthe conduits 18 and 19, drawing thedisintegrated fuel into the conduit 13.'. The fuel conduit 18 leads toasuitable hopper, which is preferably common to.V all the fuel deliveryconduits of the nozzles of the furnace.

he nozzles are all duplicates, each prov20 for manual independentcontrol of each v nozzle.

21 represents a pipe manifold connected with the various nozzles of theseries, which is connected with the supply pipe 22.

The fluid admitted into the supply pipe 22 is automatically controlledby draft and boiler pressures. This is accomplished by connecting thevalve 23 which controls the iuid within the supply pipe 22, withautomatic damper regulator mechanism. This mechanism isdiagrammaticallyillustrated herein, and its specific details ofconstruction may be of any design now commercially approved and wellknown in the art. 24.represents a cylinder provided with a piston orplunger element, actuated by the steam pressure of the boiler; the pipeconnection between cylinder and boiler are omitted in the drawings, butit may be of any well known form. In fact, any means may be employed forproducing motion con'- trolled` by the steam pressure of the boiler.

25 represents a' piston rod connected with a bell crank lever26 throughan intermediate vlink 27. One arm ofthe belll crank lever is providedwith a weight 28, adjustable thereon, by which the pressure control isregulated.

29 represents va connecting rod, 4one end of which is connected to thebell crank lever 26, with its opposite end connected to a rock shaft 30,suitablyv journaled and projected into the boiler flue 31;

32 represents a damper plate secured to the shaft 30, for regulatingthedraft. The boiler pressure actuates the bell-crank lever 26transmitting motion to the connecting rod and rock-shaft 30, swingingthe damper 32 within the furnace flue, resulting in the properregulation of the furnace draft.

33 represents a connecting rod providing an intermediate connectionbetween the damper shaft 30 and the stem of the valve 23,A wherebyysimultaneous control of the damper 30 and iuid pressure valve 23 isobtained, producing a correlative operation, in

increasing, decreasing, or maintaining the thermal umts of the furnace,cordinate with the boiler pressure. Thus, when the draft is opened thefuel supply to the furnace is increased and vice versa, the air orvaporous fluid pressure, fuel and draft conditions correlativelyproportioned to support perfect combustion at all times, whether for ahigh or low degreeof heat, and a definite boiler pressure approximatelymaintained, at aneconcmy in fuel consumption, and substantialelimination of smoke and with the services of a skilled firemandispensedwith.

It is obvious -that the general details of construction hereinillustrated may be variously modified without effecting a departure frommy invention, and the nozzle spray may be other than of longitudinalform.

Having described my invention, I claim 1. In a furnace, a combustionchamber, an arch forming the top of said chamber having a coincidentliner plate at the rear end thereof, a series of nozzles longitudinallyembedded in said arch supportingly engaged in said liner plate, each'longitudi lnally apertured .to jet a spray of fuel into'-` vsaidcombustion: chamber, and an injector on each nozzle exterior of thefurnace cornbining two conduits, 'a fuel supply and a uid pressure foradvancing the fuel within l the nozzle.

2. In a furnace, a combustion chamber, an.

arch forming the top of said chamber havj ing a coincident liner plateat the rear end' f pressure advancing the fuel within the nozzle, and avalve controlling the Huid pressure to the injector.

In testimony whereof, T have hereunto setmy hand.
